PATENT oFnca' 'SYUBMARINJE SAFETY nnvrcn. r

Application filed March 29 Another very important objectof the invention resides in the provision of adevice of this nature which will enable the crew of the rescue vessel to let down food, oxygen tanks, and other necessary paraphernalia for maintaining life in the submarine.

A further important object of the invention resides in the provision of a device of this nature which is simple in its construction, inexpensive to install, easy to manipulate, and thoroughly efficient and reliable With the above and, numerous other objects in view as will appear as the description proceeds, the invention resides in certain novelvfeatures of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a fragmentary section through the upper double deck of the submarine showing a portion of the conning tower an the features of my invention.

Figure 2 is a longitudinal vertical section through one of the safety devices.

Referring to the drawing in detail it will be seen that the numeral 5 denotes the outer portion and the numeral 6,the inner portion of the double deck of the submarine through openings of which extend a tube 7 terminating exteriorly and interiorly of the submarine. Caps 8 and 9 are threaded on the outer and inner ends of the tube 7 respectively.

Adjacent nally threaded as gaged therewith having a 12 depending therefrom.

the inner end the tube is interat 10 with a plug11 en- T-shaped handle In case the submarine becomes disabled and is resting on the bottom of the ocean or the like, the crew of the submarine releases a reel device 14: and lets up a buoy 15 attached to a cable 16 windable in the reel device. v

The rescue vessel will let down a diver who will remove the cap 8 and substitute therefor a coupling 17 with which is threadedly engaged a tubular member 18. A conduit 19 is engaged with'the tubular member 18. A plug 20 is threaded in the lower end of thetubular member 18 struction,

gated handle 21 depending therefrom down into the tube 7 terminating immediately above the plug 11. As soon as the diver has made the necessary connections the crew of the submarine will remove the cap 9, and the plug 11 and then access may be had to the handle 21 to unthread the plug f 20 which may be drawn down in the submarine thus a'lfording communication 'between the submarine and the rescue vessel. Anchoring devices 23 are threaded on the tube 7 and bolted as at 24 to the deck portions 5 and 6. i A

Obviously food and paraphernalia may be lowered to the submarine crew and if the parts are of sufficient diameter members of the crew may be drawn up therethrough. Thecoupling 17 is in the form of a reducer as the diameter of the tubular device 18 is less than the diameter of the tube 7 so that the plug 20 may be readily drawn through the tube 7 whendisengaged from the lower end of the tubular device 18.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof. Thepresent embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it will attain the features of advantage enumcratedas desirable in the statement of the invention and the above description. It will be apparent that changes in the details of conand in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any ofits advantages.

Havingthus described my invention,'what' I claim as. new is: v r

1. A submarine safety device of the class described comprising a tube for extending between the outer and inner portions of the upper deck of a submarine, means for anchoring the tube in place, a plug threaded in the inner end of the tube, a coupling on the outer end of the tube, a tubular member engaged in the coupling, a conduit leading upwardly from the tubular member, a plug threaded in the upper end of the tubular member and an elongated handle depending from the last mentioned plug and terminating immediately above the first mentioned plu A Qi A submarine safety dense ofthe class described comprising a tube for extending between the outer and inner portions of the upper deck of a submarine, means .for vanchoring the tube in place, a plug threaded in the inner end of the tube,a coupling on the outer end of the tube, a tubular member engaged 1n the eoupllng, a condult leading upwardly from the tubular member, a plug
